How To Install Terminal Services in Application Server Mode in Windows 2000 (306626)

SUMMARY

Terminal Services provides remote computers access to Windows-based programs that are running on the server. Microsoft Windows 2000 Server and Microsoft Windows 2000 Advanced Server includes Terminal Services Client Software to support 16 and 32-bit Windows-based clients. In remote administration mode, Terminal Services provides access to physically or logically distant servers. In Application Server mode, Terminal Services provides a multisession environment for server-side computing. This step by step article describes how to install Terminal Services using the Application Server mode.

Installing Terminal Services

There are three components necessary to understand when you are installing and enabling the Windows 2000 Terminal Services. The following list briefly describes these components:

• Server - The computer in which nearly all of the computing resources reside that will be used in the Terminal Services networking environment. The server will receive and process the keystrokes and mouse movements that take place at the client computer. The server displays the desktop and running applications within a window on the client computer.
• Messaging - This communication occurs between the server and clients by way of the Remote Desktop Protocol (RDP). RDP is an application-layer protocol that relies on TCP/IP.
• Clients - The computer on the network from which it is possible to open a window containing a terminal session. In this window is the remote desktop running on the server. Applications and windows that are opened on this desktop are actually running on the server.

Enabling Terminal Services in Application Server Mode

To enable Terminal Services in Application Server mode on the domain controller, the information technology (IT) administrator logs on to server as the administrator and performs the following procedures.

To enable Terminal Services:

1. Click Start, point to Settings, click Control Panel, and then double-click Add/Remove Programs.
2. Click Add/Remove Windows Components to start the Windows Components Wizard. In the Components list, to add or remove a component, click to select a check box. A shaded box indicates that only part of the component will be installed. Select the Terminal Services check box, and then click Next.
3. In the Windows Components Wizard with Terminal Services selected, click Details to see what is included in the component. You will see the two following sub-components:
   • Client Creator Files - Enables the creation of installation floppy disks for Terminal Services Client computers.
   • Enable Terminal Services - Enables the Terminal Services software on your computer.
4. Click Next to continue.
5. On the next screen, you are prompted to install Terminal Services to run in one of two modes:
   • Remote Administration - This mode permits two Terminal Services client connections to the server. This mode does not require licensing, but allows only members of the Administrators group to access the server. This is an excellent choice for non-Terminal Services servers, to enable remote control-type access to remote servers.
   • Application Server - This mode permits more than two simultaneous connections by non-administrators, but requires the Terminal Services Licensing service to be installed on a domain controller (for which you can use any server in a workgroup environment). A Terminal Services Client Access License is also required for non-Windows 2000 Professional clients.
     
     NOTE: Terminal Services Licensing is a required component that licenses clients on a Terminal server in Application Server mode. For computers that are in a Windows 2000 domain, Microsoft recommends that you do not enable Terminal Services Licensing on the same computer with Terminal Services.
6. In Terminal Services Setup, verify that Application Server mode is selected, and then click Next.
   
   NOTE: In Terminal Services Setup, you may see programs listed that will not work properly when Terminal Services is enabled. You need to reinstall these programs for multisession access by using the Add/Remove Programs tool after you enable Terminal Services.
7. In the next screen, click the appropriate option to specify whether you want permissions to be compatible with Windows 2000 Users or with Terminal Server 4.0 Users. Use the Permissions compatible with Windows 2000 Users option for the most secure environment in which to run applications.
8. In Terminal Services Licensing Setup, specify whether you want the license server to serve your entire enterprise or your domain/workgroup, and then provide the directory location for the database. Wait for the installation to finish, and then click Finish. In the Add/Remove Programs window, click Close.

NOTE: The required files are copied to your hard disk, and you can use server software after you restart the computer.

Troubleshooting

1. If an application is not working properly, it may be due to one of the following reasons:
   • Applications that lock files or DLLs may not run properly because there is the possibility that more than one user will try to use the application at the same time.
   • Applications that use the computer name or IP address for identification may have trouble if more than one user at a time attempts to run the application.
2. The e-mail address that you provided is not valid; Verify that the e-mail address is valid.
